Portal port cranes are mainly used for loading and unloading outdoor cargo yards, storage yards, and bulk cargo, with metal structures resembling portal frames. Two legs are installed below the load-bearing main beam, which can walk directly on the ground track. There can be cantilever beams at both ends of the main beam.
The new gantry crane is divided into two types:
Single chain door port crane is a type of lifting machinery specially used in ports, docks, and shipyards. It has a small investment and is used for loading and unloading containers, miscellaneous items, and bulk cargo on the apron before loading and unloading. It mainly includes the following units: a sturdy steel frame for the crane, a lifting mechanism, a variable amplitude mechanism, a slewing mechanism, and a walking mechanism.
The four-bar linkage port crane has been widely used in port loading and unloading, as well as material handling in shipyards and metallurgical industries. Its main structure consists of a steel frame, lifting mechanism, variable amplitude mechanism, slewing mechanism, walking mechanism, lifting device (grab bucket, container lifting device, hook and electrical device), electrical equipment, and other safety accessories.
1. HD electric single beam overhead crane can be widely used to handle materials in workshops
and warehouses of many industries.
2. For example, mechanical manufacturing. Warehouse. Logistics. Food.
3. Material handling situation in paper and electronic industry workshops.
4. The lifting hoist adopts M5 working class, which doubles the lifting speed.
5. Motors with ABM German brand motors.
6. The travel motor uses SEW European brand in a motor gear motor.
7. Crossing and long-distance driving are variable driving speeds.
8. The electrical components are made of Siemens brand.
9. The protection level is IP 54 high level.
10.Under ISO standards, work categories can reach A5/M5.
Characteristics of bridge crane:
1) Single welded box girder
2) DIN/FEM standard deflection
3) Full length CNC cutting of the complete web plate with high deflection accuracy
4) High quality automatic welding and non-destructive testing
5) Shot blasting Sa2.5 of the complete beam after welding, stress release
6) Installation of high-pressure bolts between the main beam and legs, ensuring a lifelong safe connection
7) Compact gear motor drive, stepless control, hardened gear, safety disc brake IP55
8) High protection level IP55, F level, 40% version
9) Excellent driving performance, stepless control, smooth movement
10) . All elevator and crane movements are independent and can operate simultaneously.
11) . The company's independent core technology in WHL type wire rope electric hoist.
